Patented Aug. 27, 1935 UNITED STATES My invention relates toabag'feedingmac lfiiiieea'ndL particularlyto a machine adapted to feedbags from a hopper to a bag lling machine andthe placing of the bag onthe bag iilllingv A chiies v forlling bags through a valve left4 intl'leba'gv for filling purposes. By means ofsuch a'valve: in a bag-vli1',V is `poss ible to ll'a bag after the baglhasl been completelysealed except for the valve opening.

This and various otherobjects, features of Lscf tice i'njY the art toYll` such bags by means Yof a bagA filling machne'having a spout adaptedto be inserted throughthe'" valve" opening infthe bag. Y

' As therevshowma container 9 vadaptedlto contain Rrior to my inventionthe operation Y-of feeding the bagtothe Vmachine and placing the bag Vonthefllingfspout ofthe bag filling machine has been performed manually.'This operation adds greatly rtc'thej cost of operation `ofv suchbaglling, machines and is also dangerous totheperson doing this work. i

It is,v therefore, an object ofjmy present VinVention to provideamachine which will automati cally feed bags to be" filled to abagjllingmachine and automatically place such fbagson `the arrangement,construction* and operation lare plainlyshown and described and v willbehest understood by reference toithe accompanying drawings showing apreferred embodiment of my invention,v in which: Y

the bag'filling spout 8, is shown in Fig. 1'. As there shown, the track63 extends from the bag lsorting and dropping mechanism to the bag llingmachine 1.y 1 The other tracks 60, 6 I and 62,

fwhilenot shown clearly in this view, extend on parallel lines with thetrack 63'. The tracks each have a dropped portion 13 at a point adjacentthe The trolleys 58 and 56 are each operatively connected with anendlessconveyor 14, whichnis driven by a'drum 15 driven by a reversibleelectric motor 16. The conveyor 14 passes over a sheaved pulley 11y,secured tothe bag filling machine 1, and over a sheaved pulley-18secured to the bag sorting and Y Vdropping mechanism.

A wedge 19 is secured at a point adjacent the bag receptacle 41 and insuch a position as to run 'betwee'the inverted U-shaped member1|l on thebag carrier 55, and asimilar wedge is secured to the bag filling machine1 at a` position adjacent the iilling spout-8. ,i jl f Aj valve openingrod `8| is 'mounted adjacent the bag filling spout 8. This rodA tapersat its end and extends to a point on a verticalv line runningV throughthe point ofibeginning of the ,dropped portion 13of-the track 63. Therod `8| is so placed that its initial contactwiththe valve inthe bag`Ill is at :the lowest portion of the valve. The rod, 8 I and-itsmountingare shown in Figs. 4, 5 and 6.. As shown in these views, the rod8| telescopes within a casing 82 by` compressing` the spring 83contained therein. The casing r82 is securedvto a'V portion of the bagfilling machine 1, and actsltosupport the rod 3|,in its operativepositionfas shown in Fig. 1;

A cam slot 84 a pin 85 secured to the rd 8|extends intothe slot 84 and.causes the rcd 8| toberotatedjasit ispushed into the casing |32.` Therod 8| lis so formed. that this'rotative movement causesv the taperedpoint of the rod 8| to be rotated after it comesin contact with thevalveiin thebag' I 0.'
